DIN2391 Cold Drawn Steel Tube For Water Cooling Pipe
Description:
DIN 2391 cold drawn steel tubes are high-precision tubes commonly used in various applications, including as water cooling pipes. Here's a detailed description of these tubes:
Standard: DIN 2391 specifies the dimensions, tolerances, and technical delivery conditions for seamless precision steel tubes.
Steel Grades: Common grades include St35, St45, St52, which differ in their carbon and alloy content.
St35: Low carbon content, good weldability.
St45: Higher carbon content, better mechanical properties.
St52: Contains additional alloying elements, higher strength and toughness.
Carbon (C): ≤ 0.22%
Silicon (Si): ≤ 0.55%
Manganese (Mn): 1.60%
Phosphorus (P): ≤ 0.025%
Sulfur (S): ≤ 0.025%
Chromium (Cr): ≤ 0.30%
Nickel (Ni): ≤ 0.30%
Molybdenum (Mo): ≤ 0.08%
Mechanical Properties:
Tensile Strength: Varies with grade; for St52, typically around 600-700 MPa.
Yield Strength: Approximately 520 MPa for St52.
Elongation: Minimum of 14% for St52.
Surface Finish: High-quality surface finish achieved through cold drawing, which enhances aesthetic and functional properties.
Dimensional Accuracy: High precision in dimensions and tolerances due to the cold drawing process.
Cold Drawing: Involves pulling the tube through a die to reduce diameter and wall thickness, improving surface finish and mechanical properties.
Annealing: Often involves annealing to relieve stresses and improve ductility.
Water Cooling Systems: Ideal for use in water cooling pipes due to high precision, excellent thermal conductivity, and resistance to pressure.
Automotive Industry: Used for hydraulic lines, fuel injection lines, and other precision components.
Mechanical Engineering: Suitable for use in machinery where precise and reliable components are required.
Hydraulic and Pneumatic Systems: Widely used in systems requiring high-strength and precise dimensional tubes.
Heat Exchangers: Used in heat exchangers due to good thermal properties and surface finish.
High Precision: Tight dimensional tolerances ensure a perfect fit and efficient performance in applications.
Excellent Surface Quality: Smooth surface reduces friction and wear, beneficial in dynamic systems like water cooling pipes.
Enhanced Mechanical Properties: Cold drawing and annealing processes improve strength and ductility.
Versatility: Suitable for a wide range of applications due to its mechanical and thermal properties.
Durability: High resistance to mechanical stress and environmental factors, ensuring long service life.
Size Range: Available in various diameters and wall thicknesses to meet different application requirements.
Tolerances: Manufactured with precise tolerances for outer diameter, inner diameter, and wall thickness to ensure consistency and reliability.
Quality Control: Includes various tests such as dimensional inspection, mechanical testing (tensile and hardness tests), and non-destructive testing (e.g., ultrasonic testing) to ensure product quality.
Certification: Supplied with certification according to the relevant standards and customer requirements.
DIN 2391 cold drawn steel tubes are high-precision, high-quality tubes ideal for water cooling pipes and a variety of other demanding applications. Their excellent mechanical properties, precision, and surface finish make them a preferred choice in industries ranging from automotive to mechanical engineering.
